Not a straw man at all. Its sadly typical of the complete ignorance of Defence among the average Canadian. They see the Gripen as an easy cheap Fuck Trump move primarily because their ignorance of most defence matters allows them to think its easy and cheap . A throwaway subject that when I start asking questions like how many Fighters does Canada need, how long does it take to train Pilots and where are our Airbases and how many are there. Blank stares and more swigs of beer. Appally lack of basic information except absolutely sure it will Fuck Trump.
Ok, so what bearing does that have on the conversation on this site?
I know where both of our fighter bases are, I have worked on both, though thankfully only ever posted to one. The pilot pipeline is long and has choke points, but that doesn't mean we should plan to maintain the status quo.
I know Canada needs more than 88 fighters, because we will lose some to technical issues, pilot error, or some combination of both. That's before we even get into the reality that in a war, we will lose aircraft and pilots. Buying more F-35s right now is pretty unpalatable politically, so our options are hope we never lose an aircraft, or buy a second fighter and make them here.
1) Creating a Gen4 Manufacturing facility in Canada isn’t going to be economically viable.
The goal isn't profitability, it's capability. If we can't make even 4.5 gen aircraft, what are we going to do in a real war when our 88 F-35s are all used up and America is too busy replacing their losses? Throw sticks and angry words at the enemy?
2) Saab has no Gen 5 Experience and at this point is an aimless orphan sitting around in the Gen 6 area (to be fair Canada is still sitting at the door).
So we partner with an experienced aircraft manufacturer as equals rather than being the perpetually outside "customer". It has already been mentioned that Germany is looking at Saab as a potential partner for their 6th gen fighter. Germany, Sweden, and Canada as partners is a lot better than Canada outside of everything, hoping big daddy America will let us have some toys eventually.
3) At this junction in time no one is going to invest in a Gen 4 Fighter, as a new addition.
At the outbreak of WWII nobody was buying modified whaling ships as warships either... But when it came down to it, what could be made was worth far more than fancy plans that didn't exist and couldn't be made.
The ship sailed, the only viable option is the F-35 for Canada.
Canada already owns F-35s... so in a way you're correct. The F-35 is viable, and already a reality. As I mentioned above though, 88 isn't enough for a real fight, and being at the back end of the order line behind America is a terrible way to plan to go to war. The Gripen isn't as stealthy as the F-35, but it is far from useless, and when a real war kicks-off, we(the collective West) will need as much industrial capacity as possible to keep the fight going, and much of that capacity will be used to build "good enough" systems like the Rafale, Typhoon, Gripen, etc...
